Support plugin configuration in tauri.conf.json
I'm struggling to integrate Oauth into Tauri 2.0. I'm following the examples for this plugin but I'm not sure what is going wrong. I'm getting a Option::unwrap() on a None value error that crashes my app whenever the rust function is invoked.
Has anyone come across this before?
My backend is running on localhost:8000 and I have set the plugin ports 8005-8007
My setup
Cargo
[dependencies]
tauri-plugin-oauth = "2"
src-tauri\capabilities\default.json
"oauth:allow-cancel",
"oauth:allow-start"
tauri.config.json
"plugins": {
"oauth": {
"ports": [8005, 8006, 8007],
"response": "OAuth process completed. You can close this window."
}
lib.rs
use tauri::{command, Emitter, Window};
use tauri_plugin_oauth::start;
#[command]
async fn start_server(window: Window) -> Result<u16, String> {
start(move |url| {
// Because of the unprotected localhost port, you must verify the URL here.
// Preferebly send back only the token, or nothing at all if you can handle everything else in Rust.
let _ = window.emit("redirect_uri", url);
})
.map_err(|err| err.to_string())
}

Has anyone come across this before?
I don't think anyone has reported this to me yet.
Does this also happen if you completely remove the plugin from tauri.conf.json?
I'll be unavailable until Saturday (or maybe Sunday, we'll see) so can't take a closer look until then.
Does this also happen if you completely remove the plugin from tauri.conf.json?
It only happens after I modify lib.rs to handle the oauth plugin, otherwise I have not come across it.
No worries if you are unavailable. I will try to trouble shoot / work around, and will share if I find a solution.
It only happens after I modify lib.rs to handle the oauth plugin, otherwise I have not come across it.
Just to be clear, with and without the plugin config in tauri.conf.json? Without modifying lib.rs the plugin won't even be compiled into the app so that part makes sense.

Thanks for clarifying, I reinstalled and removed the plugin from tauri.conf.json which has resolved the error.
What isn't working yet though is emitting the url from the window. If I open a Login window and open on onUrl listener, I don't receive anything. Am I doing something wrong?
I followed the example:
backend running on localhost:8000 oauth entry localhost:8000 oauth redirect localhost:1420?token={...}
I don't really understand why the url isn't being emitted.
lib.rs
use tauri::{command, Emitter, Window};
use tauri_plugin_oauth::start;
#[command]
async fn start_server(window: Window) -> Result<u16, String> {
start(move |url| {
// Log the captured URL to the terminal
println!("Captured URL: {}", url);
// Emit the URL to the frontend
let emit_result = window.emit("redirect_uri", url);
// Log if the emission was successful or failed
if let Err(e) = emit_result {
eprintln!("Failed to emit redirect_uri event: {:?}", e);
}
})
.map_err(|err| err.to_string())

ok that's good but still something i have to look into since the config you had was technically correct.
oauth redirect localhost:1420?token={...}
This looks wrong. 1420 is likely the frontend port, not the plugin's port. You have to redirect to the plugin's port for the event to trigger.
I ran into this myself with an erroneous "oauth": {} in my tauri.config.json while trying to figure out why I was getting "oauth plugin not found" (which was really just me needing to get my head around main.rs vs. lib.rs). I obviously didn't need it, and the issue reported here was resolved by removing the entry in tauri.config.json, but I just wanted to drop a note that I saw the behavior as well.
Hi just wanted to comment that i too faced this issue and removing the "oauth": {} in the tauri.config.json worked amazingly. Just wanted to say that @FabianLars for your work here man. Do let me know if you every need help with working on some issues here, new to rust but would love to be of help.
Thanks, much appreciated. This lib is fairly small so not much to work on really but i'll keep your offer in mind (feel free to look around once in a while :P )
For this issue itself i'm kinda leaning towards closing this as wontfix for now. The ports were never read from tauri.conf.json and the response reading was completely broken (hence this issue was opened). I don't think i've showed the tauri.conf.json as a possible configuration option anywhere in this repo either.
Otherwise this would require a bit of a refactor of the rust api to match official plugins to be able to read the config in the rust start function.
For now i'll rename this issue and see what kind of feedback i'll get.
